Dairy cow ispods (Porcellio laevis) are great when used as terrarium custodians or 'clean-up crew' and will live and breed well in bioactive set-ups.
As adults, they may attain a length of up to 20mm long. Dairy cow isopods are also useful as a livefood for many reptiles and amphibians and have the advantage of a high calcium content due to their calcarious exo-skeleton. If they are to be used as food, they are best served up in a smooth-sided dish in much the same way as mealworms or calci-worms. To thrive and become established in the terrarium, they need to be in a constantly damp and humid microclimate which normally means that they hide away for much of the time under branches, rocks or within the substrate.
Your woodlice will be delivered in a plastic container. The sides of the plastic tub are perforated to provide maximum ventilation with minimum risk of escape.
To keep the isopods healthy we would recommend you continue to feed them on a nutritious vegetable and fruit diet or with insect food.
